SIPHON APPARATUS.

SPECIFICATION forming part of Letters Patent No. 374,726, dated December 13, 1887.

Application filed January 5, 1887., Serial No. 223.444.

(No model.)

To all whom it may concern.-

Be it known that I, HENRY AYER, of Bos ton, county of Suffolk, State of Massachusetts,

have invented an Improvement in Siphon Apparatus, of which the following description,

in connection with the accompanying drawings, is a specification, like letters on the drawing representing like parts.

My invention relates to a siphon apparatus [0 especially adapted for draining cellars or other places that become flooded from time. to time, the main object of theinvent-ion being to provide a siphon which, when once filled,will remain filled and ready to begin to operate whenever liquid accumulates in the place to be drained.

The invention consists in features of con slruction hereinafter described, and pointed out in the claim.

The drawing shows, mainly in section, a siphon apparatus embodying this invention.

The part A, from which the liquid is to be removed, is represented as a cellar, and the apparatus may be used to advantage wherever there is an obstacle-such, for instance, as the wall B between the part A to be drained, and the lower conductor receptacle, 0, to which the liquid is to be delivered, and the said obstacle B makes it inconvenient or impracticable to provide a drain-passage direct from the part A to the partO, so as to drain directly by gravitation. The wall or obstacle Bin such cases may be passed over by a siphon, a, which may be of usual construction, and will operate in the usual manner to carry oflliquid from the higher level at A to the lower level, 0, in the usual manner after the siphon-tube has been once exhausted of air, so as to cause the liquid to rise in it by atmospheric pressure; and the 0 main feature of the invention consists in providing means for stopping the flow of liquid through the siphon while the mouth or inlet end of the siphon is still submerged, so that the said siphon will remain full of liquid and ready to start again when required without having to again exhaust the air from the siphon, as has to be done with apparatus of usual construction after the siphon has conveyed away the entire amount of liquid and become emptied. In order to effect this result the shorter branch or inlet portion of the sisiphon.

The valve-chamber b, valve 0, and float d are all contained in a tight reservoir, 6, placed 6;

at such distance below the general level of thepart A to be drained that the said part A will be drained and left wholly dry, while the reservoir e and the recess or depression containing itmay remain wholly or partly filled with the liquid. The said reservoir 6 may be provided with inlet-openings e, the lower edges of which may be about at the level to which the liquid is to be drawn down and at which the float d will nolonger besufficiently buoyed to keep the valve 0 unseated. When the liquid drawn from the part A into the recess A enters the reservoir 6 through the openings 6' and rises above the predetermined level represented by the dotted line 6 it buoys up the 7 float d, which unseats the valve 0 and permits the liquid to flow into the chamber 12 and out through the siphon a, assuming that the said siphon has once had the air exhausted'and been filled with liquid by the atmospheric 8o pressure. The liquid will then flow out through the siphon in the usual manner, and if the capacity of the siphon is greater than the inflow of liquid from the part A to the reservoir 0 the level of the liquid will be gradually lowered 'until it arrives at the level 0", when the float d'will sink, close the valve 0, and thus stop the flow of liquid through the siphon, which will remain filled, and the parts will remain in this condition until more liquid 0 accumulates in the reservoir 6, when the valve will be opened and the operation again begin, as before described. The valve 0 is thus always submerged in the liquid, and it is consequently easy to keep it tight, and even if it were not absolutely tight it would not destroy the vacuum in the siphon,as would be the case if the said valve were not immersed in the liquid, and the only effect that would ensue would be the slow leakage of water from the zoo reservoir 6 out through the siphon a.

In order to have the siphon always ready to operate, it is therefore necessary only that the amount of liquid left in the reservoir e'when the valve is closed should be greater than the amount that will be withdrawn by leakage or evaporation during the interval in which no more liquid collects in the reservoir 6.

In order to insure a more certain operation of the apparatus and to prevent backflow through the siphon under any circumstances,

IO the longer or delivery end of-the siphon a euters the lower portion, f, of a valve-chamber, f, which is provided with a transverse partition, f above the discharge-orifice of the siphon, said partition having an opening, f :5 controlled by a valve, g, working in the part f of the said chamber above the partition f The valve-chamberfis at alower level than the predetermined level 6, down to which the liquid is to be drawn by the siphon, and when the said liquid flows it raises the valve g and passes from the portion f of the valve chainher into the outlet portion f* thereof, which is provided with an outlet-passage, h, through which the liquid is finally discharged, and as the liquid will always remain in the valvechamber'f up to the level of the outlet h the valve g will also always be submerged and work tight.

While the apparatus described is especially useful for draining places that are likely to be flooded only after long intervals of time-as, perhaps, once or twice a year, or even less frequentlyit is obvious that it may be used as a part of any apparatus in which a siphon is to have an intermittent operation or is required to remove liquid from a tank or vat of any kind whenever the liquid accumulates therein.

I claim- The combination, with the siphon a, of a tight chamber, b, communicating with the inlet end of the siphon and provided with an inletopening, a reservoir extending above the said chamber, and a valve controlling the said inlet-opening, and a float in said reservoir connected with said valve to actuate the samehy the rise and fall of the liquid in the reservoir,

substantial] y as described.
